' A TTORNEY Patented Dec. 25, 1934 UNITED. STATES I PATENT OFFICE Y 7 1,985,427 I v FLEXIBLE FERBULE William H." Richardson, Hamden, Conn. Application January 6,1934, Serial No. 705,638

Claims.

This invention relates to new and useful improvements in flexible ferrules and has particular relation to a flexible ferrule to be used in connecting the sections of a fishing rod.

An object of the invention is to provide a ferrule of improved construction whereby a fishing rod having sections connected by the improved ferrule will not be so likely to .breakat theferrules or joints connecting its sections.

10 Another object is to provide a ferrule which will flex as the rod is flexed whereby the rod will throughout its entirelength. I 1

A further object is to provide a ferrule as stated and which is of simple construction, attractive in appearance. and of light weight.

Other objects and advantages will become apparent from a consideration of the'followingdetailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it-will be understood that the invention is not limited to. the details disclosed but includes all such variations and modifications 'as' fall within the spirit of the. invention and the scope of the appended claims.

In the drawing: Fig. 1 is an elevational view showing the improved ferrule or joint in use and connectingtwo adjacent sections of a fish pole;

showing the condition of the joint with the pole flexed;

Fig. 3 is an elevational view of the male fer-' rule member; Fig. 4 is a similar view of the female ferrule member; j Fig. 5 is a longitudinal sectional view through the improved joint; v Fig. 6 is a transverse sectionalviewythe view being taken substantially Fig. 1; a

Fig. 7 is an elevational view illustrating the invention as incorporated in a golf club; and

. Fig. 8 is a longitudinal sectional view-through 7 and female members respectively of the ferrule or joint, the. said members being designated 12 and 13, respectively.. ,LThe male ferrule member 12 may have a tubular end portion .14 receiving an end of the rod section 10 and the other end out anyv tendency to stretch the metal at eith 15 of this membermay be tubular orsolid as along the line 66' of,

drawing, at 10 and shoulder 16 is formed.

The female ferrule member 13 may be formed of tubing and includes an end portion 1'7 telescopingly receiving an end of the rod section 11 and also includes an end portion 18 of a length substantially equal to the length of the reduced end portion 15 of the male ferrule member. Intermediate its

end portions

17 and 18 the ferrule member 13 is provided with longitudinally extending slots 19 between which are formed have a substantially" uniform flexing action lands 20. The slots 19 are arranged in staggered relation and ateaoh of its ends each slot terminates in a circular portion 21. It will be understood that the end portion 18 of the ferrule member 13 extends or includes that portion ofthe member between its free end 22 and the beginning of the slots 19. Also, it will be noted that the free .end. 22 is pressed to provide a bead.

The slotted portion of member'13 or the lands 20 between the slots 19 of the member 13 are pressed or bowed outwardly whereby the member is somewhat barrel shaped.

Members

12 and 13 may be secured to the rod sections 10 and 11 in any desired manner and it is preferred that the members have a tight fit on the rod sections.

Rod section llenters only into the end tion'of said member.

/ If desired the members Fig. 2 is a view somewhat-similarto Fig. 1 but may be cemented o h p tive r d, ections and may be wrapped with cord as at 23, the cord being. tightly wound and shellacked.

female ferrule member 13.

When connecting therod sections 10 and 11 the end portion 15 is introduced into the end portion 18 and fits snugly therein and the telescopic engagement is limited since the shoulder 16 of member 12 will abut the bead '22 ofthe member 13. Therefore, the end portion, 15 does not enter into the intermediate slotted portion of the member 13. This slotted portion renders the member 13 flexible and in the use of the rod the joint will flex as indicated in Fig. 2. Such flexing results in the land or lands at the outer sideof the curve straightening or flattening while the land or lands at the inner side of the curve are further bulged as This improved joint therefore permits of a substantially uniform flexing or bending of the fishing rod withclearly shown in said Fig. 2.

Heretofore, the joints or ferrules connecting the adjacent sections of a fishing rod have been so constructed that for the length of the joint or ferrule the rod has been rigid and would not flex for a length of several inches. These joints constitute the Weak point or points in the rod since the strains caused by the stoppage of deflection or flexing at the ends of the ferrules causes a concentration of strains at these points and such action is responsible for a large percentage of rod breakage. Should the male ferrule. member .enter into the slotted intermediate portion of the female ferrule member then flexing is prevented and in the present construction such engagement is prevented and this together with the-slotting of the female ferrule section provides a flexible joint or connection between the rod sections whereby deflection may be substantially uniform:

through the entire length of the rod.

Ferrules have, in the past, been made of brass or German silver both of which are soft metals and since the ferrules aremade as thin-as possible to reduce weight it has been necessary that the meta-lot the ferrules be hard drawn'and the metal is so strained in this operation that in. the

that above described. For example, it may be in- .corpora'tedzin. a 'golf club :as suggestedin Figs. '7

and 8. In the construction illustrated the shaft of the club extends into the hosel to the point 26. That portion of the hosel between the shank end-28 and the club head 27 is hollow and longitudinally slottedzas at 28. These slots are staggered and the lands between the slots are bulged outwardly so =that'the head 2'2 may flex relative to the-shaft 25. In this construction the lands at the outer side of the bend will straighten and those. at.;the.:,:inner side bulge as aboveset forth.

The width of. these slots .and'the wall As above suggestedthe slots should-'runinto 9 round holes and are preferably'zstaggered'relatively so that bending strain will not :be'concentrated in sharp corners or in a single'line circumferentially of the ferrule. slots are made all of the'same length it: is poshaving thev individual slots of :somewhat' greater length without increasing the slotted area.
